Sure, you read reviews and take recommendations from friends before you buy a new cellphone, but have you ever stopped to consider what the inventor of the cellphone uses on a daily basis? C-SPAN has, and recently took the opportunity to ask the man himself, Marty Cooper, that very question during a wide-ranging interview. While Cooper said that he has used an iPhone previously, he recently passed it on to his grandson in favor of a Motorola Droid, which he says he chose because he wanted to get more experience with Android. But that's not all, Cooper also revealed that he carries a Jitterbug as well for when he just wants to make phone calls. Surprising for a pioneer of mobile technology? Not exactly, as Cooper actually co-founded Jitterbug with his wife, who he credits with inventing the phone. Head on past the break to watch the complete interview.
